Origin and History
London Broil, contrary to its name, is not originally from London, nor is it a single cut of meat. The term "London Broil" refers to a cooking method rather than a specific cut of beef. This dish traditionally utilizes a flank steak or top round, both of which are tough cuts of meat. The name "London Broil" is believed to have been coined in North America in the mid-20th century to describe a marinated beef dish that was broiled or grilled to tenderness. Over time, it became a popular choice for budget-conscious families due to its simplicity and delicious results when properly marinated and cooked.
Regional Variations
While the dish is common across the United States, its preparation can vary depending on regional preferences. In some parts of the U.S., the meat is marinated with a blend of soy sauce, garlic, and Worcestershire sauce, while others may incorporate ingredients such as vinegar, lemon juice, or even red wine to enhance flavor and tenderness. In the Midwestern and Southern regions, where grilling is popular, London Broil is often prepared on the barbecue, adding a smoky flavor to the meat. In contrast, those in colder climates may prefer to broil it in the oven, ensuring the dish is enjoyed year-round.
What Makes London Broil Unique?
London Broil stands out from similar beef dishes due to its distinct preparation and cooking method. Unlike steaks like ribeye or filet mignon, which are typically cooked by grilling or pan-searing, London Broil is marinated for several hours (or even overnight) to tenderize the meat. This marinating process not only makes the meat more tender but also infuses it with a rich, flavorful profile. Additionally, the unique "broil or grill" technique creates a crispy, caramelized exterior while keeping the inside juicy and tender, a combination that is rarely achieved with other cuts.
Where is London Broil Typically Served?
London Broil is commonly served as a family dinner dish, often accompanied by side dishes such as mashed potatoes, roasted vegetables, or a fresh salad. In restaurants, you may find London Broil as a steak entre, served with a variety of sides. Due to its ease of preparation and hearty nature, its also a great dish for outdoor grilling and summer cookouts. It is frequently featured at casual family gatherings or barbecues, where guests enjoy the rich flavors and tenderness of the meat paired with their favorite sides.

Delicious! I followed recommendations from other reviews since my London broil was thick. I added 2 tablespoons of lemon juice to the marinade to help tenderize the meat and let it marinate for 48 hours in a ziplock bag. I broiled the meat for about 7 to 8 minutes per side, then wrapped it in aluminum foil and let it rest for 10 minutes before slicing. I've attempted London broil multiple times with disappointing results, but this recipe was the best. Will definitely make it again!

Thank you, Jill! I prepared this dish yesterday following Josie's recommendations. I used 3 tablespoons of lemon juice instead of Worcestershire sauce, added 2 teaspoons of fish sauce, 1 teaspoon of ground ginger, substituted chili sauce for ketchup, and included 2 teaspoons of garlic powder. I divided the four pounds of food into four one-pound portions. My wife and I enjoyed one portion, one is stored in the refrigerator, and the other two are in the freezer. Grateful for the tips from all the talented cooks out there. As a beginner, I appreciate your guidance!

This London Broil is the most delicious I have ever tasted. I increased the marinade amount for a 2-lb cut, scored it, and placed it in a double ziplock bag. The meat marinated for 48 hours before broiling for 8 minutes on each side (cooked to medium rare perfection). Absolutely tasty.

Absolutely fantastic marinade! On a gloomy rainy day, I quickly seared the meat on each side for 5 minutes in a cast iron skillet on the stovetop and then finished it in the oven. I added a dollop of herbed butter on top as it rested, and the results were phenomenal. Can't wait to make it again!

I absolutely adore this recipe! I have made it several times now and made a few tweaks to make it even more delicious. I like to add some rice vinegar, lime juice (when I'm out of lemon), a generous splash of sodium-free smoke sauce, cayenne pepper, and a touch of habanero sauce (just half a teaspoon). The habanero adds a fantastic flavor without making it too spicy. I prefer using a ziplock bag over foil for marinating—it's much less messy. Remember to flip the bag occasionally. A crucial step for me is saving a bit of the marinade (kept separate from the beef) to brush on top of the roast while grilling. I recommend marinating overnight for the best results. This dish is so flavorful that no gravy is needed!

Added hot sauce but couldn't taste it. The dish was incredibly flavorful though! I marinated the meat for 24 hours in a zip-loc bag, but I think my tough cut of meat would have benefitted from an extra 12-24 hours of marinating. I noticed some reviews mentioning lemon juice, so I'll try adding that next time.
